The current timeout logic for Control Queue-Pair (CQP) OPs does not take into account whether CQP makes progress but rather blindly waits for a large timeout value, 100000 jiffies for the completion event. Improve this by setting the timeout based on whether the CQP is making progress or not. If the CQP is hung, the timeout will happen sooner, in 5000 jiffies. Each time the CQP progress is detetcted, the timeout extends by 5000 jiffies. Signed-off-by:

Do not track physical state separately from host_link_state. Deduce physical state from host_link_state when required. Change cache_physical_state to log_physical_state to make sure host_link_state reflects hardwares physical state properly. Reviewed-by:

There is a mixture of mutex and spinlocks to protect receive context (rcd/uctxt) information. This is not used consistently. Use the mutex to protect device receive context information only. Use the spinlock to protect sub context information only. Protect access to items in the rcd array with a spinlock and reference count. Remove spinlock around dd->rcd array cleanup. Since interrupts are disabled and cleaned up before this point, this lock is not useful. Reviewed-by:

Michael J. Ruhl authored
The rcd array can be accessed from user context or during interrupts. Protecting this with a mutex isn't a good idea because the mutex should not be used from an IRQ. Protect the allocation and freeing of rcd array elements with a spinlock. Reviewed-by:

When DC is shut down (by e.g. disconnecting the cable), the driver should use host_link_state to get port's current physical state. This is due to the fact that physical state is read from DC's CSRs and when DC is shut down and state is changed, its registers are not impacted. Reviewed-by:

Most user verbs pass user data to the kernel with the inclusion of the ib_uverbs_cmd_hdr structure. This is problematic because the vendor has no ideas if the verb was called by a legacy verb or an extended verb. Also, the incosistency between the verbs is confusing.

Enables multiple Interrupt vectors. Driver is requesting the max MSIX vectors based on the number of online cpus and creates upto 9 MSIx vectors (1 for control path and 8 for data path). A tasklet is created for each of these vectors. NQs are assigned to CQs in round robin fashion. This patch also adds IRQ affinity hint for the MSIX vector of each NQ. Signed-off-by:
